项目摘要

The purpose of this research is to establish the following methods so as to respond the social needs of rece.ving electrical power without interruptions even under such uncertainties as sudden faults.1. Evaluation method of flexibility of the electrical power systems planning which always be a multi-objective optimization problem,2. A new efficient random scenario creation algorithm,3. Distribution planning method in which fault conditions are taken into consideration.The followings as the reserch result of this research project.1. A new evaluation method of the flexibility of the power systems planning is developed. In the method, the concept of inverse projections of the solutions is used to evaluate the flexibility. The developed algorithm is tested by developing the computer program of the algorithm. More-over, a new flexible generator maintenance scheduling method is established as a by-product of this research.2. A new dfficient random scenario creation algorithm in which the concept of the chaos and the genetic algorithm are used is developed and tested. The adequacy to use the concept of the chaos in creating a random scenario is investigated. However, the clear answer is not found whether the chaos can be used in creating the scenario, so far.3. A new distribution systems planning method in which the fault cases and multi-year planning are taken into account is developed and tested by developing the comoputer program.The above research results are presented in many international and domestic conferences. Some of the fine results are submitted to the transactions of IEE of Japan and IEEE.Some of the results are published in the transactions as shown in the references in the next page.

这项研究的目的是建立以下方法，以响应社会需求。即使在突发故障等不确定因素的情况下，也能不间断地恢复电力。电力系统规划的灵活性评价方法一直是一个多目标优化问题，2.一种新的高效的随机情景生成算法，3.考虑故障情况的配电规划方法。提出了一种新的电力系统规划柔性评价方法。在该方法中，利用解的逆投影的概念来评价柔度。通过编制算法的计算机程序对所开发的算法进行了测试。此外，作为本研究的副产品，还建立了一种新的灵活的发电机检修调度方法。将混沌概念和遗传算法相结合，提出了一种新的高效随机场景生成算法，并进行了测试。研究了在随机场景中使用混沌概念的充分性。然而，到目前为止，还没有找到混沌是否可以用于创造情景的明确答案。提出了一种考虑故障情况和多年规划的配电网规划新方法，并通过编制计算机程序进行了验证，上述研究成果已在国内外多次会议上发表。一些优良的结果被提交给日本的IEE和IEEE的交易。一些结果被公布在交易中，如下一页的参考文献所示。
